Porto Airport is straightforward once you separate the three queues: airline check-in or bag drop, security, and passport control if you are flying outside Schengen. The right arrival time depends on your airline, luggage and destination, so check those before setting off rather than using a one-size-fits-all rule.
How early to arrive
Porto Airport currently recommends checking in at the counter 90 minutes before a Schengen flight, 120 minutes before a European non-Schengen flight and 180 minutes before an intercontinental flight. Those are check-in desk recommendations, not a promise that you can arrive at the terminal then and still make boarding. Your airline’s bag-drop closing time takes priority. Online check-in does not remove the bag-drop queue if you have luggage to check. Check the airport’s current check-in guidance and your airline app.
Non-Schengen flights also need passport control after security. If you are flying to the UK, for example, do not treat the gate as though it were a domestic departure; leave time for that extra step.
Security and liquids
Some Porto security lanes have newer scanners that allow up to two litres of liquids, but the airport says you cannot know in advance which lane you will use. Its conservative advice remains containers of up to 100 ml in a clear 1-litre bag, presented separately. I would pack to that rule rather than risk losing a bottle at the tray. Medicines and baby food have exceptions; check the airport’s security page for what to do with them.
Getting there
Metro Line E serves Aeroporto station directly. Check the Metro do Porto journey planner for the first or last service that fits your flight. A taxi or ride-hailing car makes more sense with heavy bags, a very early departure or an address far from the metro. If you are transferring to a train, plan the trip to Campanhã separately; the airport metro is not a train connection at the same station.
Food before boarding
If you have not checked in yet or are meeting someone, Deli&Cia has a landside counter before security as well as airside locations. After security, A Francesinha is on Level 2 if you want one last Porto sandwich; Douro is another Portuguese-food option. Check the airport’s restaurant directory for current hours and whether the place is before security, after security or in the non-Schengen area. That last detail matters: you cannot pop back landside after passport control.
Before leaving home, check the live departure board and your airline’s flight status. Keep your boarding pass and passport accessible, then relax once you are through the checks that apply to your flight.
